When is the last time you changed your fuel filter? It might be as easy as buying a fuel injector cleaner...gumout works pretty good. Whats your fuel pressure at?
1991 mustang cutting out.
1500 to 2000 rpms my 5.0 h.o bogs down and then it will get past 2000 rpm and clear up. did complete tune up. timing at 15 everything. i am pretty sure a vacuum somewhere is leaking to cause when it revs down it will sit just about my idle then bout 5 second later it will rest at idle. help please.
